Qmail Rocks on Ubuntu
A stock Ubuntu server install will need a few additional packages to support Qmail Rocks.
apt-get install openssh-server apt-get install build-essential apt-get install libssl-dev apt-get install openssl
Virtual Hosts
When you run config-fast you set your main STMP host. If you need other virtual hosts then you must edit your rcpthosts file.
# ./config-fast mail.vinylinteractive.com Your fully qualified host name is mail.vinylinteractive.com. Putting mail.vinylinteractive.com into control/me... Putting vinylinteractive.com into control/defaultdomain... Putting vinylinteractive.com into control/plusdomain... Putting mail.vinylinteractive.com into control/locals... Putting mail.vinylinteractive.com into control/rcpthosts... Now qmail will refuse to accept SMTP messages except to mail.vinylinteractive.com. Make sure to change rcpthosts if you add hosts to locals or virtualdomains!
